I have a big problem with odoo v9... It's that my suppliers, give
me their price lists based in a discount over the recommended sale
price.

In Odoo v8 I could create supplier price lists rules to assign
discounts per categories but in odoo v9 supplier price list rules
are gone and I only can assign a price cost per product... this is
very cumbersome.

What alternative method can I use to assign product costs per
categories? Any solution for my user case?
